It didn't come as a shock to Kitty how some of the younger students (like Emmeline) were disturbed by what they were doing. Honestly, if she didn't completely trust the professors she might have been a little disturbed too. Professor Meyer's description of what the tears could do was incredibly disturbing.

"Maeroro!" she hissed, pronouncing My Ro-Ro while making the upside down U. It worked! To her immense surprise, tears started dripping down from the strings of the tree. Four of the tears fell into her vial, but two more splattered on the ground.
